A family of Microsoft relational database management systems designed for ease of use.
I created a subfolder below where my backend database used to exist then moved it there (on the same server). Once moved, I relinked the FE to the back end tables' new location and set the "Compact/Repair on Close" option. I cannot say if the folder move, relinking the back end tables and/or the Compact/Repair on Close is what fixed it, but it is fixed. Over 3 weeks later, no data corruption errors - Knock on wood. Sometimes the simpler solutions are the ones you try last.
I just tried this on a user's system. Fingers crossed and I'll report back if they stay stable for a week or so. I'm sick of getting these calls every day; I have a large number of clients so it really adds up in time down the drain not to mention the loss of goodwill. (Sorry about the whining.)
